Derby South MP Dame Margaret Beckett has said that even if she had to vote 50 times she still would not vote for the Prime Minister's Brexit deal.

Dame Margaret spoke as the House of Commons was bracing itself for Tuesday night's vote. It is being held more than a month after it was originally due to take place.

The previous vote was dramatically called off at the last minute because Theresa May's Government sensed that defeat would be inevitable.

Currently, it is estimated that around 100 Conservative MPs will vote against the deal. Dame Margaret (Lab) and other MPs have not changed the way they were due to vote originally.

Dame Margaret said: "It is a disastrously bad deal and not what those who voted to leave the EU in 2016 were thinking of at all.

"But there is no need for any of it. The Government could stop this and let the House of Commons decide what is best. But Theresa May is exhibiting unbelievable obstinancy. We are being asked to accept EU rules but not have a say in them and that is a fatal flaw.

"I think the way forward is a people's vote and it would be sensible to take it back to the country."

Mid Derbyshire MP Pauline Latham (Con) is likely to vote the deal down also but she says that it is no means clear yet what MPs will be voting for.

She said: "The speaker, who has torn up the rule book, hasn't made it clear whether or not any amendments will be allowed and if they are they could make a difference to the motion and the withdrawal agreement. I will vote against any amendments.

"If a vote of no confidence in Mrs May and the Government is tabled then I and most of the Conservative MPs are likely to vote with the Government. There has never been a time of so much uncertianty."

Mrs Latham added that she was surprised to receive from the Unite union, at Rolls-Royce, a request for her to vote against the Brexit deal.

She said: "I don't think they think it will protect workers' rights even though for the past two years the union has been convinced that no deal would be the worst thing for the company."

Comservative MP for Erewash Maggie Throup will vote to support Mrs May's Brexit deal and says her position has not changed throughout the process so far.

She said: "My decision has not been taken lightly. It is important to recognise that the deal our Government has negotiated with the EU extensively delivers on the result of the referendum by returning control over our money, laws and borders.

"In contrast, since the referendum, Labour has consistently failed to develop a credible alternative plan to deliver Brexit and is now actively considering a second referendum, which risks Britain’s departure from the EU in March 2019.

"Indeed, whilst the current deal delivers on the substance behind the six tests which Labour laid out, they still plan to vote against it in a cynical attempt to bring down the Government and disrupt the Brexit process. Now is not the time to play party politics.

"I fully accept that this deal may not be perfect in every single way, however the very nature of a negotiation means that both sides must be willing to give and take. To this end the Government has won important concessions from the EU, which, from the outset nobody thought would be possible."

The vote is expected to take place between 7pm and 9pm on Tuesday night.
